ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 746,198, dated December 8, 1903.

Application filed August', 1902. Renewed May 2,'1903. Serial No. 155,426. (No model.)

ed for use for vehicles and machines of every description, and the object thereof is to construct a roller-bearing for preventing objectionable movement of the bearing-rollers and diminish friction, wear, and noise of the roller-bearings. y

-The invention further aims to construct a bearing-roller in such a manner that'it can be thoroughly lubricated when set up for use.

The invention `further aims to construct a' roller-bearing which' shall'be simple infits construction', strong, durable,efficient` in its .operation, and comparatively inexpensive to set up.

To this end the invention consistsof the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed` out in the claims hereunto appended.

ln describing the invention in detail,A reference is had to the accompanying drawings, forming a part of this specification, ywherein likereference-n u merals denote the same parts throughout theseveral Views,'and in which- Figure l is an elevation of myimproved roller-bearing as applied to the journal of a vehicle-axle.

:is 'further provided-With openings 8', which register with-the openings in the protuber- For the purpose of illustrating the rollerbe'aring in use I have shown the same in con-k nection with an axle-journal and a journalbox, and referringtothe drawings by reference-numerals 1 denotes the axle-journal of a vehicle, and 2 the journal-box, which consists of a cylindrical shell, provided with end pieces 3 4, respectively, and supported from the vehicle in anysuitable manner.

Any form of journal-box which is suitable can be employed in connection with the rollerbearing. Y

The roller-bearing comprises a pair of rings integral with its inner Iface-a circumferentially-extendingseries of protuberances 7, which are hollow and substantially in the Each of the rings ances 7. The protube'rances 7 of one ring are arranged opposite to those of the other.

The referencenumeral 9 denotesa series of bearing-rollers. vEach of these rollers 9 has at each end an inwardly-extending recess l0 of truncated cone-shaped form to correspond with the shape of the protuberances 7. The protuberances of the rings are adapted lto project in the recesses lO of the bearingrollers.

The recesses-10 terminate yin a cylindrical-shaped opening 1l through the remaining portion of the bearing-roller 9. By such a construction it will be evident that the bearing-rollers arehollow, but that the inner bore of the bearing-rollers is not of the same diameter throughout. The periphery 4opening 15 extends through the thickened portion of the roller nearone end thereof and terminates into the cylindrical opening 1l, and the other opening 16 extends through .the thickened portion of the roller-'that is,

the thickest part thereof near the opposite of each of the bearing-rollers 9 is formed r 6s 5 6, respectively. 'Each ofV these rings has.'

endand terminates in the opening 11. rlhe bearineuoliers are each mounted upon a pair of protuberances 7, and after theyare placed in such position a spindle or journal 17 is extended through the two protnberances 7 and the roller 9. By this arrangement the rollers are secured to the rings and are retained a suitable distance apart. The rollers V9 when in such position are adapted to engage with the journal 1, as the supportingrings 5 (i therefor are mounted upon the journal 1, one supportingn'ing preferably near the outer end thereof and the other supporting-ring near the inner end thereof.

The function ofthe spiral groove 12 in each of the rollers 9 is to carry a suitable lubricant for lubricating the journal 1 for decreasing friction. The function of the openings 15 1h' is to carry a suitable lubricant to lubricate the spindle orjournal17 aswell to lubricate the walls of the truncated recesses 10 in the rollers 9. As before stated, the spiral groove 12 does not extend entirely across the periphery7 of each of the rollers, but terminates at a point adjacent to each end of the rollers 9. From such a construction it is evident that there are no weak edges to break on the periphery of the roller,which would be the case if the groove extended throughout the entire periphery of the roller. Therefore it is evident that a plain surface is left all around the periphery of the rollers 9 at the ends of the rollers. The truncated recesses in each end of the rollers are adapted to [it loosely the protuberances `7 on the supporting-rings 5 (i, and the journals or spindles 17 of each roiler 9 extends through the rings, rollers, and protuberances, as before stated. By such an arrangement when the rollers revolve they areprotected from the twistingrstrain to which they are subjected during the operation of the journal l. The proturbances 7 also 1n ain tain a system of separation for the rollers, as they keep them a suitable distance apart at. all times and out of contact with one another, insuring a simple and durable construction to reduce friction tothe minimum. The protuberances 7 on the rings 5 6 also strengthen them at their weakest part as well as support the journals 17, upon which the rollers 9 revolve. j

In Fig. 5 the roller-bearing is shown as set up to what I term the three-ring formation-that is, in addition to the end rinus 6 a central supporting-ring 18 is ein pioyed having each of its faces provided with cylindrical protuberances` 19. Between the ringr 18 and end rin; 5 is arranged a series of bearingrollers and between the other end ringl G and the ring 1S is arranged another series of hearing-rollers. The construction of the bearingroliers and end rings is the saine as that hereinbefore referred to. Therefore the same reference-numerals are applied thereto.

In Fig. 6 is shown the roller-hearing as set up to what I term the single-ring formation, and it consists of the ring 20, with the protuherances 21 formed integral with each face thereof, the protuherances being of the same construction as hereinhefore referred to, and through the protnberances extends the journal or spindle 22, which projects from each of the protuberances 21 and carries on each projecting end a bearing-roller 23. The bearing-rollers 23 are of the same construction as hereinhefore referred to.

In Fitz. 8 the rings 2t are provided with ribs 25, which are arranged between each of the rollers 26, the latter beiner of the same construction as hereinbefore referred to, and these ribs 25 are adapted to hold the rollers together as well as addingr strength to the rolier-bearing. In this construction the spindles for supporting the rollers 25, as weil as the protuberances on the rings, are also einployed and are of the same construction as hereinbefore referred lo.

From the fort-racingr construction it will be evident that a miler-hearing is provided in which the bearing-rollers are retained in parallelism, and thereby give all the advau tages due to the employment. of hearing-roliers Without any of the disadvantages usually resulting" therefrom, and it is thought the many advantages of a roller-bearing;` constructed in accordance with the foregoing' description, taken inconnection with the acconipanying drawings, can he readily under stood, and it will also be noted that l have devised a simple, inexpensive, and novei form of roller-bearing which can be readily set up for journals employed in vehicles, machines, and apparatus of all (ilescriptious, and it will furthermore be evident that changes, vari-fe tions, and modifications may be resorted to without departing' from the spirit of the in vention or sacrificing any of ils advantages, and I therefore do not wish to restrict myself to the details of construction herein before described, land as shown in the accompartying,r drawings, but reserve the right to ,make such changes, variations, and modifications as come properly within the Scope of the protection prayed.

In Fig. Si of the drawings a slightly-modi- Ytied arrangement of parts is shown-that is to say, there are two sets of liearing-roliers 9 arranged between the axle-spindle i and the inner surface ot' the hub 27. To receive the rollers 9, the hub 27 is provided with iuterual recesses,formingt shoulders 282i). The rines 5 and 6 are similar in all respects to the rinus 5 and (5, heretofore referred to, the saine being provided with the protuberances which project into the recesses in the ends ofthe bearilnnrollers. One of the rinus 5 bears against the shoulder 2.), whereas the other rinpY 5 is held in place by the nut 30, screwed upon the threaded end of the spindie l. One of the rings 6i bears against the shoulder 28, whereas the other ring (in, which cooperates therewith, bears against the co1' lar 31, which, as usual, is formed upon tht.` axle-spindle. The operation of this form ot my invention is identical with that heretofore described, the only dierence being that the rings by which the two series of rollers 9 are supported are arranged in separate and -independent pairs.
